Materials Data on Fe6O5F7 by Materials Project
Abstract
Fe6O5F7 is zeta iron carbide-derived structured and crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are four inequivalent Fe+2.83+ sites. In the first Fe+2.83+ site, Fe+2.83+ is bonded to two equivalent O2- and four F1- atoms to form FeO2F4 octahedra that share corners with eight equivalent FeO3F3 octahedra and edges with two equivalent FeO2F4 octahedra. The corner-sharing octahedra tilt angles range from 45–60°. Both Fe–O bond lengths are 2.02 Å. All Fe–F bond lengths are 2.19 Å. In the second Fe+2.83+ site, Fe+2.83+ is bonded to two O2- and four F1- atoms to form FeO2F4 octahedra that share corners with eight FeO3F3 octahedra and edges with two FeO2F4 octahedra. The corner-sharing octahedra tilt angles range from 37–55°. There is one shorter (1.91 Å) and one longer (1.94 Å) Fe–O bond length. There are a spread of Fe–F bond distances ranging from 2.00–2.12 Å. In the third Fe+2.83+ site, Fe+2.83+ is bonded to three O2- and three F1- atoms to form FeO3F3 octahedra that share corners with eight FeO2F4 octahedra and edges with two FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 37–60°. There are a spread of Fe–O bond distances ranging from 1.93–2.01 Å. Theremore »
